Abstract
Disclosed herein is a scaled method for producing substantially aligned carbon nanotubes by depositing onto a continuously moving substrate, (1) a catalyst to initiate and maintain the growth of carbon nanotubes, and (2) a carbon-bearing precursor. Products made from the disclosed method, such as monolayers of substantially aligned carbon nanotubes, and methods of using them are also disclosed.

21. A method for producing substantially aligned carbon nanotubes, said method comprising depositing onto a continuously moving substrate,
(1) a catalyst to initiate and maintain the growth of carbon nanotubes, and (2) a carbon-bearing precursor, growing nanotubes inside of a chemical vapor deposition (CVD) reactor at conditions that promote the growth of substantially aligned carbon nanotubes on the catalyst support material.

38. A method for producing substantially aligned carbon nanotubes, said method comprising depositing onto a semi-continuous or continuously moving substrate:
-
(1) a catalyst to initiate and maintain the growth of carbon nanotubes, said catalyst comprising iron, cobalt, nickel, platinum, lead, palladium, copper, gold, or any combination or alloy thereof; and (2) a carbon-bearing precursor at a flow rate per unit substrate surface ranging from 10 ml/(cm2min) to 400 ml/(cm2min), growing nanotubes inside of a chemical vapor deposition (CVD) reactor at a temperature ranging from 600 to 1,100 degrees Celsius, wherein said substrate comprises a flexible or rigid tape, wire, ribbon, cylindrical, or ring substrate of platinum, palladium, iridium, iron, cobalt, nickel, chromium, carbon, silicon, aluminum, magnesium carbon, combinations, alloys or oxides thereof.
